Q3. A single cylinder, single acting air compressor has a swept volume of 0.055 m³ and a clearance volume of 0.0030 m³ and runs at 500 rpm. The air is compressed from 1 bar and 27°C to 6.0 bar. The index of compression and expansion is 1.29.

(a) Sketch the cycle on a pressure - volume diagram.

(b) Calculate EACH of the following:

(i) the volumetric efficiency

(ii) the mass of air delivered per second

(iii) the indicated power.

Note: For air C_p = 1.005 kJ/kgK C_v = 0.718 kJ/kgK
